Abstract:
A hip prosthesis includes a femoral component with an elongated stem for seating within an elongated, longitudinally split sleeve having an exterior porous ingrowth surface. When implanted as a unit into the medullary canal, the femoral component stem wedges tightly into the sleeve to correspondingly press the sleeve into intimate and tight fit engagement with the bone. During normal postoperative use, any bone subsidence is accompanied by further wedging of the femoral component stem into the sleeve for maintenance of a secure mechanical interlock between the bone and prosthesis. However, in the event of failure for any reason, the femoral component and split sleeve are removable relatively easily to permit hip reconstruction with a new prosthesis.
